Abstract
The utility model relates to a mechanical device, specifically to a self-servo braking device for a brake. The self-servo braking device comprises a housing body and an end cover arranged on the housing body, wherein a spline sleeve is arranged in the housing body and sleeved with a friction sheet assembly and a pressure plate; one side of the pressure plate is in transmission connection with a rocker through a link mechanism; a steel ball is arranged between the pressure plate and the housing body. The self-servo braking device is characterized in that a sunken part is arranged inside the housing body, wherein the sunken part is cylindrical part with the spline sleeve served as the centre. The link mechanism is a shifting block fixedly arranged on the rocker; a shifting block groove is arranged at one side of the pressure plate, and the tail end of the shifting block is arranged in the shifting block groove. The braking device is compact in structure and convenient to install, and the housing body is reasonably stressed.
Description
Technical field
The utility model relates to a kind of mechanical device, is a kind of self energizing effort braking device specifically.
Background technique
Braking device commonly used is fixedly mounted on the end of semiaxis on the vehicle such as automobile, tractor, promotes the friction plate assembly through platen and is sticked together, and realizes the purpose of braking.This braking device is installed on the elongation line of length direction of semiaxis, and volume is big, it is inconvenient to install, housing is stressed unreasonable.
Summary of the invention
The purpose of the utility model provides the self energizing effort braking device of a kind of compact structure, easy for installation, housing reasonable stress.
For reaching above purpose, the technological scheme that the utility model adopted is following:
The described a kind of self energizing effort braking device of the utility model comprises housing, is installed in the end cap on the housing; Be provided with spline housing in the housing; Be set with friction plate assembly and platen on the spline housing, a side of said platen is in transmission connection through linkage mechanism and rocking arm, is provided with steel ball between platen and the housing; It is characterized in that: the inboard of said housing has sunk part, and said sunk part is to be the cylindrical of center with the spline housing.
Said linkage mechanism is the shifting block that is fixedly mounted on the rocking arm, and a side of platen has the shifting block groove, and the end of said shifting block is installed in the shifting block groove.
Adopt technique scheme, this braking device compact structure, easy for installation, housing reasonable stress.
Description of drawings
Fig. 1 is an embodiment's of the utility model a structural representation.
Fig. 2 is Fig. 1 embodiment's a sectional view.
Embodiment
Like Fig. 1, shown in Figure 2; The said a kind of self energizing effort braking device of the utility model comprises housing 1, is installed in the end cap 7 on the housing 1; Be provided with spline housing 23 in the housing 1; Be set with friction plate assembly 5 and platen 4 on the spline housing 23, platen 4 and spline housing 23 coaxial settings, but can relatively rotate.One side of said platen 4 is in transmission connection through linkage mechanism and rocking arm 16, and said linkage mechanism is the shifting block 14 that is fixedly mounted on the rocking arm 16, and a side of platen 4 has the shifting block groove, and the end of said shifting block 14 is installed in the shifting block groove.Be provided with steel ball 3 between platen 4 and the housing 1, have conical socket on the platen 4, steel ball 3 is arranged in conical socket; When rocking arm 16 rotates; Drive platen 4 through shifting block 14 and rotate, steel ball 3 turns to the more shallow place of conical socket, moves axially thereby promote platen 4; Compressing friction plate assembly 5 makes its adhesion braking.
The inboard of said housing 1 has sunk part, and said sunk part is to be the cylindrical of center with spline housing 23.Vehicle semiaxis 6 corresponding these sunk parts that insert are fixedly connected spline housing 23 through connecting bolt 20 when installing with live axle, and housing 1 is fixedly connected with axle sleeve.After the installation, because the sunk part of housing 1 is inserted in the end of semiaxis 6, installation volume reduces, and housing 1 is connected firmly with semiaxis 6, is not easy displacement.
